In this poster we present three developments related to the Galactic O-Star Spectroscopic Survey (http://adsabs.harvard.edu/abs/2011hsa6.conf..467M{GOSSS})...

Using the near-infrared spectral stellar library of Cenarro et al. (J/MNRAS/326/959), the behaviour of the MgI line at 8807Å and nearby TiO bands is analyzed in...

Magneto-acoustic and Alfvénic waves are ubiquitous in solar coronal loops, possibly being excited by photospheric motions. It is not clear, though, how these...

A generalization of the Theoretical Spectral Access Protocol (TSAP) standard called Simple Self-described Service Protocol (S3P) has been used to search and...

In addition to clearly biological microbial mats, lava tubes contain many non-biological appearing mineral deposits that contain life. The discovery that such...

Mid-infrared observations are a vital tool for the study of a wide range of astrophysical phenomena. However, ground-based mid-infrared detectors must overcome...

JEM-EUSO is a space observatory that will be attached to the Japanese module of the International Space Station (ISS) to observe the UV photon tracks produced...

Simple gravitational lens models usually suffice to reproduce the positions of lensed quasar images, but they have problems to reproduce their optical flux...

We have considered the influence of gravitational microlensing on the spectral line profiles generated by a relativistic accretion disc model. We discuss...
